BUTTON-WORKING MACHINE.

SEECIFICATION forming part of Letters Patent No. 793,533, dated June 27,1905.

Application led July 2, 1902. Serial No. 114,069.

`blank to the finished blank ready to receive the usual and necessaryperforations.

In my improved machine the entire operation, save the feeding of theblanks to the charging-tube,is entirely automatic and requires butlittle attention from the operator in charge. y

My invention comprises special means for feeding and positioning thebutton-blanks in their proper relation to the cutting-tool, specialmeans for holding the blanks during the turning operation, special meansfor adjusting and feeding the tool to its work, special means forkeeping the cutting-tool sharp, special means for keeping the tool andthe chuck for holding the blank free from the dust and chips taken offsaid blanks, and special means for polishing the finished blanks.

Other features and the details of my invention will be more fullypointed out hereinafter, reference being' had to the accompanyingdrawings, in which- Figure l isa front elevation of myimprovedlmtton-working machine.

Fig. 9is a partial plan view illustrating a further detail of my invention,and Fig. 10 is a detail view in elevation of a part of the mechanismshown in Fig. 9.

The machine forming the subject of my invention has been designed moreparticularly for use in the manufacture of pearl buttons. It will beunderstood, however, that its application and use is not confined tobuttons of this character, for it may be used for turning the buttonsmade of any material capable of being worked by a cutting or grindingtool.

In describing the operation of my machine I will refer to the mechanismcomprising the same under several heads, which may be designated asfollows: First, means for feeding the button-blan ks to the chuck;second, means for operating the feeding mechanism; third, the chuck forholding the button blanks; fourth, means for operating the chuck; fifth,means for setting the blanks in the chuck; sixth, means 'for operatingsaid setting device; seventh, the cutting -tool and its carrier; eighth,means for operating the cutting-tool; ninth, the sharpening device forthe cuttingtool; tenth, means for operating said sharpening mechanism;eleventh, the driving mechanism; twelfth, means for keeping the chuckclear of the material turned olf the buttons; thirteenth, means foroperating said clearing mechanism, and fourteenth, means for polishingthe finished blanks.

In the accompanying drawings, 1 represents the bed-plate of the machine,and 2 the supporting-standard. Suitably mounted beneath the bed-plateand carried by a bracket 3 is a chuck 4, adapted to receive thebutton-blank. Carried by said bed-plate is a standard 5, on which ismounted a tool-holder 6, carrying an adjustable tool 7, which may belowered by suitable mechanism, so as to bring it into engagement withthe button-blank supported by the chuck just referred to. This chuck isrotated in a suitable manner, which will be described, and as thel firstthing necessary in introduced by the operator one at a time into thetube 11, although it is obvious that the blank may be placed directly ina slide-piece 15, described hereinafter. The housing 10 referred to isarranged directly in line with thecenter ofthe button-chuck, andarranged within said housing and adapted to be reciprocated back andforth therein is the slidepiece 15, having an aperture 16, which nor--mally rests under the tube 11 and receives from the same onebutton-blank at a time. This slide is moved forward at predeterminedintervals by suitable mechanism and deposits a button-blank adjacent tothe jaws of the chuck. The slide is shown in detail in Fig. 6 and isbeveled at 17 in order that when moving forward with a button-blank itcan push out of the way a button-blank previously turned and ejected bythe chuck, but not thrown from the bed-plate, and it is also providedwith a groove 18 on the under side, which enables the end to ride overthe button-blank after the latter has been seated in the chuck. Theslide is also beveled at 19 adjacent to the aperture 16, so as to assistthe engagement by the same of the blanks fed from they tube 11.

Verma for operar/ag the feeding mec/mm.- ism.HY The sliding member 15 ismoved from and toward the chuck to feed the buttons theretoV by means ofa lever 20, carrying a toothed segment 21, which meshes with a rack 22,formed on the top of said sliding member, the housing for the same beingcut away or apertured at 23 for the free movement of said toothedsegment. This lever 2O is pivoted at 24, and at the opposite end it isconnected to a link 25, which link is attached to a slidearm 26,arranged to move in lixcd bearings 27, the movement of said arm beingcontrolled by a cam 28. A spring' 29 is connected to a hook 30 at theend of said slide-arm and to a fixed member 31 on the top of thebed-plate. The cam 28 is so formed that while it provides a gradualforward movement of the slide to effect the deposit of the button-blankadjacent to or directly over the jaws of the chuck it permits a quickrelease of the slide-arm 26 in order that the spring 29 may effect thereturn movement of the lever 2() and reset the sliding member 15 asquickly as possible. This movement is eifected entirely automatically,and the sliding member 15 engages 'a buttonblank at each operation andmoves the same forward toward the chuck. T/ie o1/M071; for /LorZf/hif/t/l/e uwn-km/s.- The chuck 5 for holding the button-blanks is supportedfrom beneath the bed-plate of the machine and is constantly rotating during thev operation of said machine. This movement necessitates theentrance of the button-blank into said chuck during this reciprocation,which will be effected in the manner shortly to be described. The chuckis formed b v radially slotting a tube 32, and thereby forming threejaws 33, which engage the button-blank. This tube is tapered below thejaws and is mounted in a suitable cup 34, which is arranged to be movedup and down by a suitable lever connection and is provided with a spring35, wherebyitmay be held in the raised position to clamp the jaws of thechuck around abuttonblank. Surrounding the cup 34 is a collar 36, havingpins 37 projecting from the same. Resting on these pins isa lever 38,pivoted at 39 under the bed-plate of the machine. This lever iscontrolled by the cam 40 and has an openingl 41 providing the cam-surfaces 42 to engage the pins 37. The depression of this lever 38 bythe cam 4() lowers the cup 34 and serves to open the jaws of the chuck,as said jaws are normally sprung outward and are only held in to engagethe blanks by the engagement of said cup 34. When the cam releases thelever 38, the spring 35 returns the cup to the raised position,closingthe jaws of the chuck. Vithin the jaws of the chuck an ejector-pin 43 isarranged, which pin passes entirely through the tube forming the chuckand is held against removal by means of a nut 44. The chuck is supportedby a short hollow shaft 45, journaled in a bracket 3. Inter-poisedbetween the bottom of the chuck-holder and a collar 43 on saidejector-rod is aspring 46,Y which tends to raise said rod, so as toeject the turned button-blank when the clamping-cup is released, saidcup having' been previously lowered by its coacting mechanism, therebyreleasing the frictional contact of the chuck upon said ejector-rod.

Vea/11s for 01m/raming t/e Chawla- As noted above, the chuck is carriedby a short hollow shaft 45, journaled in the bracket 3. This IOO bracketis cut away at 47, and carried by the As I have already said, the chuckis revolvf ing constantly as the button-blanks are fed to the same. Thesliding member for feeding the blanks to the chuck delivers said blanksdirectly over the opening in the chuck. The opening is spread, however,due to the fact that the clamping-cup for said chuck is in the loweredposition, and in order to set said blanks in the jaws of the chuck Iprovide the carried by the slide-arm 26.

finger 50, pivoted at l to ears 52, carried byv the base-plate of themachine and shown more clearly in Fig.

Verme for cpc/'ating said sett/ng Zee/06. The linger 50 is operated bymeans of a sliding rod 53, secured to one end of said finger, which rodin turn is moved by a lever 54,

'controlled by a cam 55 on the main driving- Vblanks adjacent to thechuck said cam 55,

through its connections, has moved the linger 50, so as to press itsfree end upon the buttonblank and set it in the jaws of the chuck. 'Ihecam is so timed that the finger will be released as soon as thebutton-blank has been set in the jaws of the chuck, and at the same timethe clamping-cup for said chuck will be raised and the button-blank willbe securely held. All yof this operation takes place during the rapidrotation of the chuck, and hence the movement of the parts must be quickand accurate. 'Ihe chuck is provided with a recessed portion 56, whichforms a seat for the buttonblank, so that the latter when once set inplace may be turned down to a delinite thickness no matter what itsoriginal thickness may be.

In Figs. 9 and l0 I have shown a modified forni of mechanism foroperating the settinglinger. In this form of structure this work isperformed by means of a spring 60, which is The linger 50 is normallyheld out of action by means of a coiled spring 61, and the spring 60 isemployed to throw the ling'er down into engagement with the blanks. Asthe slide is moved forward carrying a blank to be deposited in the jawsof the chuck the spring 6() is acting against the rear end of the lingerand is gradually lowering said linger, so that when the blank has beenmoved by the slide directly into position in the chuck it will beengaged by the linger and pushed into place. As soon as this is done therear end XL of the spring' 6() contacts with a pin 62 on a part of theliXed structure of the machine, releasing the linger 50 and permittingits rise by the aid of the spring 6l, so that the slide l5 can beretracted for another blank.

Ill/w cmfz'm/-ool and rits caf/'wier mec/taav'sm.-A standard mounted onthe bedplate of the machine, is provided with a vertical slide 65, towhich is adapted a sliding carrier 6, having' a tool-carrier 66adjustable in several directions, to which carrier an adjustabletool-post 67 is connected, in which is vthe springs 76.

vthe same.

mounted an adjustable tool 7. rIhis tool, as has already been noted, isemployed for turning or dressing the button-blanks and shaping them intoperfect forms ready to receive the holes. Said tool is provided with ahandle 68, whereby it may be set up to the work w hen desired.

Warum for operating the Caman-tool. MrIhe vertical movement of thesliding member 6 is accomplished by means of the lever 69, pivoted at 70to said standard and having ayoked end 71, which engages a pin 72 on thetoolcarrier, and agooseneck 73 at the opposite end, having afriction-roller 74:, which is engaged by a cam 75, mounted on the maindriv ing-shaft 8. Thls cam 1s formed so as to carry the tool intoengagement with the blank and to rest in such position until the blankis finished and then to become inactive, so far as movement of thetool-slide is concerned,

whereby the latter may be raised to carry said tool into the inoperativeposition by means of In Fig. 4 the tool is shown in operative positionworking on the buttonblank, while in Fig. 3 the tool is shown as havingbeen raised to the inoperative position.

The shammi/ag deecejbr the cittt//f/tg-tool. u When this machine isemployed for turning pearl buttons, which are, as is well known, veryhard, means must be provided for sharpening the tool at regularintervals, and such means must be automatically operated during thenormal running of the machine. For this purposel I mount on acounter-shaft 8O an emery-wheel 81, which is provided with operatingmechanism, so that it may be brought into connection with the tool afterthe turning of every fourth button. To do this, I employ the followingmeans:

Verma for operativa/0157i@ s/tarpcmfag mac/1,- mc'sna-From thespur-wheel 82, mounted on the side of the machine, an arm 83 projects,said arm being hinged at the center of said spur-wheel. This arm isconnected to the end of the counter-shaft 80. On thc face of thespur-wheel an annular rib 84 is provided, and said arm has a projection85 engaging aid rib. rI`he counter-shaft 80, carrying the emery-wheel81, is held away from the tool against the action of the spring 86 bymeans of this arm. Ata point 87, however, the annular rib 84 isrecessed, and when during the turning of said spur-wheel by its pinionsaid recess comes opposite the arm the spring 86 Will tend to force theemery-wheel into engagement with the tool. 'Ihis engagement is onlymomentary and is sufficient simply to keep said tool constantly sharp.It will be the business of the operator to keep his eye upon the tooland see that it is set up to its work and that it is engaged by theemerywheel every time the latter is moved toward emery-wheel, is drivenby means of a belt 88, which receives lts power from the pulley 48,

IOO

The counter-shaft 80, carrying the 'are ready for such movement. .arepreferably provided with suitable hubs- Awhereby they may be secured tothe main driving-shaft by set-screws. The levers engaging said cams areall provided with antifriction-rollers.

The warms for keeping the chuck clem 0f 2571/@ mfr/arial Zammel of theZry/fcsf-In a-machine of this character the material will be removedfrom the blanks in a finely-powdered state and unless removed from thechuck will tend to choke the latter and prevent the accurate adjustmentand holding of the buttonblanks therein. In order to remove this, Iprefer to employ a blast of air, which may he operated continuously orintermittently, as

desired. This structure is shown in Fig. 7 and in dotted lines inFig. 1. The end of the pipe 95 carrying such blast is arranged so as todirect the current of air against the top of the chuck, and in thisposition it will be e11- tirely clear of the operating parts of themachine and at the same time will not be so strong as to affect theposition of the blanks. To provide the necessary blast, a fan 96 iscarried by the end of the counter-shaft, which fan rotates within acasing 97, carried by the @Ism/. The fan is driven directly by thecounter-shaft 80, and either fan or casing is arranged to move with saidshaft when the sharpening mechanism is operated. If in practice thespeed of the counter-shaft is not suiiicient to provide su lIicientblast or suction, gearing may be connected to said fan from the maindriving-shaft 8, and thereby have as high speed as necessary ordesirable. The fan-casing is carried by a bracket98, which is connected,by means of a bolt 99, with a part of the fixed frame of the machine.

llkam' forpolz's/L/ag t/Leym's/ed Hrm/rsf- After the blanks have beenturned by my improved machine I may remove the cuttingtool and itsoperating mechanism and place on the machine an apparatus for polishingthe blanks. This is clearly shown in Fig. 8. The

- tool-holder is removed, and in its place a finger 100, carrying arouge-pad 101, is fixed. This device is controlled by the lever 73,which operates the tool-holder; hut in' place of the cam 75 a cam 102 isemployed. The buttons will be fed as when turning the same and themachine operated in entirely the same manner, except that the blast maybe dispensed with.

Carried by the slide 15 is a rouge-cup 103, having a scraper 104, andthis cup will be carried forward, so that on the downward movement thepad 101 will enter the cup and receive suficient rouge to polish theblanks. The movement of the pad is controlled directly by the cam 102,and said pad is moved into and out of the cup and then into the blank,the contact of the latter being suflicient to insure the properpolishing of the same. This mechanism is described and claimed in anapplication filed by me May 12, 1904, Serial No. 207,583.

Although I have shown and described my invention as having avertically-moving chuck with coacting mechanism arranged to operate upona chuck so disposed, it will be understood that said chuck may bemounted hori- Zontally and the button-blanks fed to it from afeeding-spout that will deliver them in a position toc be acted upon bya setting-linger to insert them in such horizontal chuck.
